Gate of the Hell

Gate of the Hell or Hell's Gate is a gate that connects the human realms and the demon realms. It is located in the center of Arad's Labyrinth in the Northern Continent.

It is surrounded by a powerful magical barrier and magical quicksand to ward people from entering Hell.

It is said that mana and magic came to human realm because the Hell's Gate was opened and sealing it will make magic and mana cease to exist

History
In the past, when Angels ruled over mankind, Hell was used as a place to throw sinners and those who didn't obey their orders. Hell was full of demons and mana which is not suitable for human. It is said that the intense mana presence is burdening to those who are not used to it. Demon, already living in Hell for a long time, is immune to the burden. The human who was thrown into hell plot a rebellion with the demon against the Angels. This cooperation led to various invention such as magic stone and the birth of the first Necromancer, the hybrid of demon and sinners
